Dvele Construction in North Tustin, CA | Sycamore Contractors
We provide independent Dvele construction service across North Tustin and Dvele in Villa Park, handling everything from panelized additions and prefab ADUs to finish trades and site integration. The thing that sets our Dvele work here apart is simple: North Tustin is unincorporated, so every Dvele project gets reviewed and inspected by OC Public Works rather than a city building department, and hillside lots often trigger extra grading and drainage plan checks. That changes how the factory package has to be adapted to the site, and we plan for it from day one. Call (877) 265-6284 to talk through your Dvele project in North Tustin.
Why North Tustin Residents Choose Us for Dvele Service
Dvele builds a genuinely tight panelized shell. We have worked with their custom single-family line, their prefab modular units, and their ADU packages long enough to know where the factory spec ends and the site work begins. That is the gap most North Tustin projects fall into. The factory can engineer for a generic California lot, but it cannot engineer for Cowan Heights Drive wind exposure, a 1970s electrical panel, or an OC Public Works hillside grading review.
We are not a Dvele dealer and we do not pretend to be. We are a general contractor that knows the product well enough to integrate it properly with county requirements and existing conditions. Nate Calloway, our owner, grew up in Temecula and learned construction through Palomar College’s program before running crews across Southwest Riverside County for the better part of two decades. He treats Dvele work the same way he treats every build: the factory component is only as good as the foundation, flashing, and finish trades around it. That is where we come in.
We also carry Dvele sales & service knowledge that most general contractors in Orange County simply do not have, because we have actually set, sealed, and finished these systems on North Tustin hillsides.

Common Dvele Construction Problems We Solve in North Tustin
- Moisture intrusion at module joints. Dvele’s factory gaskets and sealants do exactly what they are designed to do in a controlled assembly. But North Tustin sits at the foot of the Santa Ana Mountains, and when strong Santa Ana winds drive rain sideways and load the seams with dust and grit, those factory gaskets can fail at the module-to-site joints. We see air leaks, water staining, and early delamination at the seams. We re-seal with OEM Dvele gaskets and re-flash the joint properly for the wind direction on that specific hillside.
- Frame connections that do not pass OC Public Works hillside review. Dvele’s prefab frame connections and hold-downs are specified for factory assembly. North Tustin hillside properties often require additional seismic retrofit and hold-down reinforcement that the factory package does not include. We field-reinforce connections and add retrofit detailing at the foundation so the project passes county inspection the first time.
- Wildfire-defense gaps in the factory shell. North Tustin’s foothill location triggers wildfire-defense construction requirements: ember-resistant vents, fire-rated roofing, and defensible-space-compliant hardscaping around the structure. Factory-applied Dvele exterior coatings and flashing do not always address these site-specific requirements, which leaves the shell under-spec’d. We close the gap before the shell gets signed off.
- Mechanical, electrical, and plumbing stubs that do not line up with legacy systems. Many North Tustin homes are 1960s to 1980s ranch-style builds with original electrical panels, galvanized plumbing, and early copper. When a Dvele module arrives with MEP stubs designed for a modern panel, the original 1970s panel cannot always carry the load. We handle the panel upgrade, the service line, and the rework so the module actually functions on site.
- Foundation interface and drainage issues on sloped lots. A factory-built unit assumes a reasonably flat, prepared pad. North Tustin’s hillside lots frequently need additional grading, retaining, and drainage work before the Dvele component can be set and sealed properly. We do that site work under one contract so the factory piece and the ground it sits on actually work together.
Dvele Service in North Tustin: What Local Conditions Mean for Your Equipment
Here is the part most Dvele owners do not learn until a project stalls: in North Tustin, you are not dealing with a city building department. The area is an unincorporated island surrounded by incorporated Orange County cities, so construction permitting runs through OC Public Works and OC Planning, not Santa Ana or Tustin proper. For a Dvele project, that means plans are reviewed and inspected by county engineers, and if your lot is on a hillside, you will likely get an additional grading and drainage plan check that flatland tract cities never require. We have navigated this exact path on projects off Cowan Heights Drive and throughout the 92711 zip. On one Dvele panelized addition, our crew found the module-to-site wall joints leaking at the factory gasket line after a wind-driven rain, and the original 1970s electrical panel could not carry the new HVAC stub. We re-sealed the joints with OEM Dvele gaskets, upgraded the service panel, and scheduled the OC Public Works grading and framing inspections ourselves. The result was a weather-tight shell with signed-off county permits. That sequence, factory component meeting county checklist, is the actual work of Dvele construction in North Tustin. It is also our coverage area, which you can see on our North Tustin service area page.
Dvele Models & Products We Service in North Tustin
We work across the Dvele product range: the custom single-family home line, the panelized wall and floor system, the prefab modular units that are factory-built and site-completed, and the prefab ADU and accessory dwelling packages. Our parts approach is direct. Where Dvele’s factory spec calls for OEM connectors, gaskets, or proprietary flashing, we source the OEM part and we do not substitute. Where the spec is silent or the component is a non-structural finish, we use proven quality aftermarket materials. We stock common Dvele gaskets, sealants, and flashing components locally so a North Tustin repair does not wait on a factory shipment. If the failure is a field assembly issue, we repair it. If the component itself is compromised, we replace it. We will tell you which is which before you spend a dollar.

AfterDvele Service Pricing in North Tustin

FAQs – Dvele Construction in North Tustin
A Dvele addition in North Tustin typically lands between $45,000 and $130,000 depending on lot slope, county grading requirements, and whether your existing electrical panel can carry the new load. A full Dvele ADU package generally runs $90,000 to $220,000 once site prep, foundation work, MEP tie-ins, and county inspections are included. Hillside lots often push toward the higher end because of additional grading, retaining, and drainage work that flatland builds skip. Call (877) 265-6284 for a free, line-itemed quote on your specific project.
No, and we are upfront about that. Sycamore Contractors is an independent general contractor that services Dvele systems. We are not manufacturer-affiliated and we do not claim Dvele authorization or warranty endorsement for any part or repair. What we offer is construction follow-through: site work, structural integration, envelope detailing, and finish trades, all adapted to North Tustin’s county requirements rather than a one-size-fits-all assembly.
Yes, where the factory spec requires it. We source OEM Dvele connectors, gaskets, and proprietary flashing for structural and envelope repairs. For non-structural finishes, we use proven quality aftermarket materials and we tell you before we do it. You will always know whether a part is factory or aftermarket before it goes on the build.
The county timeline drives most of it. OC Public Works plan review, grading checks, and inspection scheduling add time that a city permit would not. A smaller Dvele repair or re-seal is often done in days. A full panelized addition or ADU typically runs weeks to months depending on hillside conditions and how quickly county inspections can be scheduled. We give you a realistic timeline up front and we do not promise what the county cannot deliver, whether your project is in North Tustin or you need Dvele service in Santa Ana.
We work across the Dvele custom single-family line, the panelized wall and floor system, the prefab modular units, and the ADU and accessory dwelling packages. If the factory built it and it needs to function on a North Tustin hillside, we can service it, integrate it, and get it through county inspection.
